PDP Success Rate (PDP SR) in 2G/3G Network
PDP Success Rate (PDP SR), is an important metric in 2G/3G mobile network. It measures the percentage of successful PDP context activations established between the mobile device and the mobile network.
A high PDP success rate, (e.g. above 95%), is generally considered a good indicator of a well-performing mobile network.
Typically PDP SR is calculated using the following formula,
PDP SR = [PDP successful activation times / PDP activation requests] * 100
